MANYANI, Kenya (AFP) - Kenya's President Mwai Kibaki on Wednesday ignited five tonnes of ivory stockpiled in the country since being seized in Singapore nearly a decade ago.

"We must all appreciate the negative effects of illegal trade to our national economies," Kibaki said. "We cannot afford to sit back and allow criminal networks to destroy our common future." "Through the burning of contraband ivory, therefore, we are sending a clear message to poachers and illegal traders.
